CVE-2022-29037
Published: 12 April 2022
Summary
CVE-2022-29037 is a medium-severity Cross-site Scripting (CWE-79) vulnerability in Jenkins Cvs. Its CVSS base score is 5.4 (Medium).
Operationally, ranked in the top 39.6% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
Jenkins CVS Plugin 2.19 and earlier contains a stored cross-site scripting vulnerability because it fails to escape the name and description fields of CVS Symbolic Name parameters when rendering parameter views. The affected component is the Jenkins CVS Plugin, which integrates CVS version control into Jenkins jobs and exposes these parameter details on configuration and build pages. The issue is tracked as CWE-79 with a CVSS 3.1 score of 5.4.
Attackers who possess Item/Configure permission on a Jenkins item can supply malicious payloads in the affected parameter fields. Once saved, the payloads execute in the browsers of other users who view the parameter display pages, enabling actions such as theft of session tokens or redirection to attacker-controlled content within the Jenkins context.
The Jenkins security advisory published on 2022-04-12 at SECURITY-2617 describes the flaw and the corresponding plugin update that resolves the missing output encoding.
EPSS for this CVE rose from a low baseline to a peak of 0.2958 before receding to the current value of 0.0039, indicating a period of increased exploitation interest after public disclosure.
